Leverage pre-existing foundational data models of SAP Business Suite entities for use in SAP HANA data mart scenarios:

    Significantly reduces complexity of data modeling tasks in SAP HANA

    Speeds up timelines for SAP HANA implementation projects

Provide semantically rich data from SAP Business Suite to SAP HANA:

? Ensures that data appropriately represents the state of business documents from ERP

? Application logic to give the data the appropriate contextual meaning is already built into many extractors

Simplicity / Low TCO:

? Re-uses existing proprietary extraction, transformation, and load mechanism built into SAP Business Suite systems over a simple http(s) connection to SAP HANA

? No additional server or application needed in system landscape

Change data capture (delta handling):

?Efficient data acquisition – only bring new or changed data into SAP HANA

?DXC provides a mechanism to properly handle data from all delta processing types
